I get 4 emails

That’s as expected, plain text and HTML, all content and excerpt.

How should I set up to receive an email only?

Why do you want to do that? Subscribe2 can send out 4 different types of email, when previewing does it not make sense to be able to see all 4 of the types that may send – it’s just a preview!

These are 4 identical emails, I only need one.

There are 4 possible emails so 4 previews are sent.

You’ve sent a screenshot of your personal notification settings that apply when the post is published.
